Ally Financial, formerly GMAC Financial, has filed the paperwork necessary for an Initial Public Offering. The Detroit News reports that the filing will go to the Securities and Exchange Commission for approval before Ally can go public; a process that could take months. The federal government, which owns 74 percent of the lending arm due to its $17.2 billion 2009 bailout, is the only party listed as a stockholder. [Autoblog]
